The complete list of upload rules can be found here, although for the forum we're much more lenient. We're mostly focused on the following:
ADDED: Do not intentionally upload "Blacklisted models." Most of them have requested not to appear here so we will respect their wishes. Also, nudity is allowed in the Fantasy section as well, and so the artwork/stories/morphs etc. can be NSFW if you choose to upload there.
A shame it needs to be pointed out, but we don't need "Can someone give me paysite content for free?" threads. If you want to trade with someone privately, you can do it in the chat room or use the site's messaging system.
